Wavelength stabilization scheme for tunable laser diode based on temperature feedback

ZHU Zhen; CHEN Liang-you; LI Hua; XING Hui

A general discussion on tunable semiconductor lasers for high speed optical communication is presented,with emphasis on SSG-DBR lasers.Then a novel temperature feedback control scheme for frequency stabilization is described. Using bias current control,absolute wavelength stabilization within 1nm has been achieved with SMSR better than 35dB in the temperature range of 20℃~70℃.This simple,effective stabilization method will play an important role in obtaining highly reliable light sources for optical network.
